RS PRO 1.25A F Glass Cartridge Fuse, 5 x 20mm

This cartridge fuse is designed to International (IEC) Standards for use globally. It is available in cartridge and axial lead form. They are ideal for providing protection to devices or internal circuits from short circuits and overcurrent. They are deliberately weaker components which, when too much current is drawn, will blow. Once the fuse has blown it will need replacing in order to make the circuit complete and allow the flow of current.

Features:
• Glass Fuse (glass body, nickel plated brass cap)
• 5 x 20 mm cartridge size
• F Speed Rating
• RoHS compliant and lead-free

Typical applications:
Cartridge fuses are a relatively cheap way of protecting electrical equipment from short circuits and overcurrent and can be used to protect electrical appliances such as motors air-conditions, refrigerator, pumps etc. They can be found in the following areas:
Industrial
Commercial
Home/Residential
Automotive

Additional information:

Why choose a glass fuse?
Glass and ceramic fuses have similar properties. Glass fuse is great for small items that don't draw a heavy amount of current and blow on a regular basis. It is easy to identify whether the fuse has blown as you can see inside it.

What size is it?
5x20 mm is a standard cartridge size and it measures approximately 20 mm long by 5 mm in diameter. They are popular in board and panel protection and will fit a compatible 5x20 fuse holder.

What Speed is it?
This particular fuse is ''F'' speed rated which means a fast acting fuse. These are designed to protect less sensitive components and are also used to protect cabling from melting or catching fire when an overload appear. Every fast acting fuse will have the exact speed stated which will be relevant to different overloads.

What are fuses used for?
For the protection of components and equipment from costly damage caused by over-current.
To isolate sub-systems from the main system once a fault has appeared

What is an over-current?
It is a setting where a circuit experiences a current that is higher than the normal operating current.

What is Breaking Capacity?
Breaking capacity is the level of current that the fuse can safely handle without exploding or rupturing. The breaking capacity of your fuse should be greater than the fault current of your electronic circuit. This particular fuse is LBC (Low Breaking Capacity).
